When you lock up your office at night, you shouldn't have to worry about your digital assets. Whether company and customer data or strategic information - everything should be stored securely and in a controlled manner. With the internationally recognized management system for data security - ISO/IEC 27001 certification - this is already a reality.

For companies or organizations that use modern cloud solutions or build on a reliable colocation environment, compliance with this international ISO standard has long been a must. After all, only those who systematically manage risks, implement clear security measures and continuously improve their processes can build trust in the long term.

ISO 27001 in detail: this is how certification with STACKIT works

From the initial analysis to the certificate: the path to ISO 27001 certification follows a clearly structured process. Here you can find out in detail which steps are crucial.

Planning with foresight

The path to ISO 27001 certification begins with a gap analysis that examines existing processes, systems and security measures and identifies security gaps. The scope is then defined in consultation with STACKIT. Whether location, department or entire company: A clearly defined scope is essential. Equally important is a competent project team that coordinates the introduction of the ISMS.

Setting up an ISMS: Identify risks, secure processes

Structured risk management is at the heart of ISO 27001. Vulnerabilities are identified, evaluated and addressed with suitable security measures (controls). These measures are implemented in accordance with the standard specifications. At the same time, central documentation is created - from access rules to binding guidelines on information security. Training courses ensure that the implementation also reaches the employees.

Internal control and management assessment

Before the external audit begins, an initial audit takes place: an internal auditor checks whether the ISMS has been implemented effectively. The company management then assesses in the management review whether the system is working and can be further developed. This check is a prerequisite for the subsequent certification audit.

Certification by an independent body

The certification audit takes place in two stages: In Stage 1, the certification body checks documents and preparations. Stage 2 is followed by an on-site audit to assess processes and the security awareness of employees. If successful, you will receive the ISO 27001 certificate. This is valid for three years and includes annual surveillance audits.

Continuous improvement

Even after certification, regular surveillance audits check the effectiveness of the system. The recertification audit follows after three years, which reviews existing processes and responds to changes in requirements. This guarantees a permanently high level of information security.

Practical tips for your entry into ISO 27001 certification with STACKIT

The introduction of an ISMS in accordance with ISO 27001 is not a sure-fire success. However, with good planning, clear communication and competent support, getting started is easy. The following tips will help you to avoid typical pitfalls, unnecessary costs and delays and to approach the certification process in a targeted manner.

  • Define the starting point - start with a gap analysis: Before you begin implementation, you should analyze the current status of your information security. A gap analysis shows which areas are already compliant and where measures are required to meet the requirements of the standard. This inventory is the basis for all further steps.
  • Secure backing - involve management at an early stage: An ISMS requires clear priorities, human resources and a budget. This only works with backing from the top. Therefore, involve the company management in the project at an early stage. The project can only be implemented successfully if the management recognizes its relevance and actively supports it.
  • Design documentation with a sense of proportion: Documentation is a central component of ISO 27001, but should not get out of hand. Keep processes, role descriptions and measures clear, understandable and as lean as possible. This not only facilitates internal processes, but also subsequent audits and regular reviews.
  • Provide employees with targeted training and raise their awareness: Technical security measures only work reliably if employees are also involved. Conduct regular awareness training to sensitize your team to risks, rules of conduct and security standards. Coached employees are often the decisive factor for the success of the project.
  • Rely on experience - bring in experts: Whether external consultants, specialized ISMS managers or experienced auditors: Get targeted support to make the certification process efficient and standard-compliant. Professionals identify typical weaknesses at an early stage and support the implementation of tailor-made protective measures in line with the ISO guidelines.
  • Plan your time realistically - and stick to it: Depending on company size, complexity and initial situation, you should allow at least six months for implementation and certification. Also keep an eye on internal efforts and costs. After successful implementation, however, ISO 27001 requires regular audits and the will to develop further.
